Title: Plasma cvd equipment
Inventor: NABETA OSAMU
IPC: H01L21/205
Filed: 1986-05-09
Abstract: PURPOSE:To perform decomposition of each material gas while preventing residues produced during decomposition of other material gas from being entrained into the forming film and to obtain a high-quality thin film, by providing and distributing several groups of hollow cathodes classified by material gases for which they are exclusively and independently used while providing anodes adjacent to the cathodes. CONSTITUTION:Hollow cathodes are divided into three rows of hollow cathodes exclusively for diborane 41, hollow cathodes exclusively for phosphine 42 and hollow cathodes exclusively for silane 43. Anodes 5 are arranged adjacent to the cathodes 41, 42 and 43. The cathodes 41, 42 and 43 and the anode 5 are connected to discharge power sources 61, 62 and 63 via changeover switches 71, 72 and 73. One of the switches 71, 72 and 73 is closed to supply the electrodes with electric power while the inside of a reaction furnace 1 is evacuated through an exhaust port 8. Thereby, the material gases supplied to the cathodes 41, 42 and 43 are decomposed by glow discharge plasma and plasma activated species are discharged from the respective cathodes 41, 42 and 43. In this manner decomposition of each material gas can be performed, while preventing residues produced by decomposition of other material gas from being entrained int eh forming film. Thus, a thin film having high quality can be obtained.

Title: Detector for micro-displacement angle
Inventor: FUJII KENJI
IPC: G01D5/30
Filed: 1981-07-08
Abstract: PURPOSE:To detect micro-displacement angles with a small size and high accuracy by amplifying the angular displacements of a turning reflection member by the use of multiple reflections between a stationary reflection member and the turning reflection member facing the same. CONSTITUTION:A reflecting mirror 1 suspended by a stationary member 2 has reflection surfaces 1a, 1b, and is located in a stationary reflecting mirror 3 having four reflection surfaces 3a-3d. The light from a light source 4 passes  through a pinhole 5 and a condenser lens 6 and reflects alternately between both reflecting mirrors mentioned above and forms images on one-dimensional image sensors 9 through a prism 7 and an imaging lens 8. When the member 2 inclines by theta from the vertical direction, the mirror 1 displaces from the mirror 3 and the inclination of the luminous flux made incident to the prism  changes largely. When it reflects n times between both reflecting mirrors, the incident angle to the prism changes by 2ntheta. This is detected from the extent at which the pinhole image moves on the sensors 9.
